Tap Magic makes a fluid specifically for tapping aluminum it's also fantastic for drilling and parting!

I've seen it used many times in other videos but never have ordered any. It's not something that's on the shelf at the local hardware store that I've noticed anyway. I'll have to make a point to order some. I'd like to try it. Thanks for the info!

Is this the grizzly 781? If it is, would you share how long the ball screws are?

[@MyRobertadams]

This is the Grizzly G8689 mill. It was a manual mill. I bought a kit for the ballscrews and stepper motors and an electronics kit for controlling it. I do not remember where I got those kits from as it many years ago.
